LOCOMOTIVE.

Specification of Letters Patent.

Application filed March 20. 1916. Serial No. 85,428.

To QZZ wh m it may concern Be it known that I. \Vumun. F. KncsnL, J12, a citizen of the. l'nited States, and resident of Altoona, Blair county, State of Penna sylvania, have. invented certain new and useful Improvements in Locomotives. of which the following is a specification.

My invention relates to railway vehicles. locomotives especiallvyand has particular reference to a structure adapted to provide for suflicient lateral motion of the vehicle bod) and frame with respect to the truck, as on curves where the front truck of the locomotive must have side motion.

()n modern large locomotives with the increased number of drivers it is difiicult to provide sutiicient truck side motion with the ordinary link suspension. and in order to obtain sutiicient side motion on curves for the front. truck of the locomotive l have 'idevised an arrangement in which the body frame is supported on the truck b v means of a rocker which swings transversely of the. locomotive and gives the required side motion.

The objects and novel featuresof myin \ention will be apparent from the following description taken in connectioi'i with the drawings in which,

Figure 1 is a side elevation of thetront end of a locomotive embodying my invention: Fig. 2 is an enlarged plan view of the pony truck shown in Fig. 1. a part of the truck being broken out. Fig. is partly a front elevation and partly a central section of the tr nck shown in Fig. 2 and is taken on the line 33 of Fig. 2. Fig. 4 is a longitudinal sectional view of the pony truck taken on the line 44 of Fig. 2. Fig. 5 is a view of the rockersupport. partly in central section: and Fig. (i is an end view of the rocker support.

The pony truck shown'in the drawings is in some respects similar to the. one shown 1 and described in my FatcntXo. 1,166,695, granted January 4, 1916. The, wheels ltl of the truck are mounted on the ends of an axle 11. The transom 12 and journal boxes 13 are madefin one piece, the journal boxes 50 :inclosing the bearings 14 wherebv the ran soinds mounted on the axle 11. For convenience the transom and journal boxes will be designated as the truck frame. The truck i'rame also has a tail brace 15 extending rearwardl-y and fulcrumed on thepin 16 around which the truck swings.

()n each side of each ol the journal boxes there is a seat 17 for pairs of bolts 18 which pass through the upper ends of Tlinl s or hangers 19 at opposite sides of the seats 17. The T-linlts l!) are connected together in pairs at their lower ends by bolts 20 as seen in Fig. 3 and the end of the'lower spring of a seriesof llatleat' springs 21 is secured between the lower ends of each pair of hangers; The springs 21 are superposed on one. another and extend longitudinally of the axle. one complete spring being mounted on each side of the axle and being hung at its ends by pairs of hangers on the same side of the axle 1.1. )[idwav between its ends each spring 21. is surrounded by a band 'lzfiwhich has an enlargement at its lower end below the spring. The enlargement is provided witlran opening extending through it for a purpose to be set forth.

The rocker It. shown in Figs. 5 and (3 consists of a casting provided with a head 2% which has two pairs of jaws on its lower side. the members 25 of the jaws being spaced 'apa rt a sutlicient distance to receive the springs .31 between them. The members 2? are also --providcd with alincd openings .26 which register with the openings in the enlargement '22-) otthe bands 22 and are arranged to receive the trunnion bolts 27 by means of which the rocker is supported or may swing ransversely of the locomotive. The head 2+ or the rocker has a flat bearing surface 2H on its upper side which is of considerable width and is tangent to the. curve passing through the curved portions 29 at the edges 0t the flat portion 28. The

head 24 also has a lug St) on its upper side rising centrally from the flat surface 28. In a particular emlaaliment of my invention the [lat portion 28 at the top of "the rocker has been made It) inches'wide so that the T-links 19 are compelled to move about 2 inches before the rocker rotates about its t'ulcrlun pin. it is desirable to have the flat of some width in order to provide a moment Patented Nov. 7, 1.916.

suspended centrall ot' the truck so that it the transom 12 and as shown in end view in Fig. 6 they taper downwardly. The 10- comotive body 31 has a body frame 32 fixed to the lower side thereof and a frame supporting casting 33 is securely bolted to the locomotive frame 32. L the supporting casting 33 constitutes a mounting for the draft gear and also a center plate to mount the frame upon the rocker R. The casting 33 has an opening 35 adapted to receive the lug on the rocker R. Suitable liners 36 may be inserted between the flat surface .28 of the rocker and the bottom side of the frame supporting casting, for the purpose of properly alining the locomotive frame 'and to compensate for wheel. journal and bearing wear. As the rocker and frame supporting casting have interfitting parts they will be kept in proper mesh and have sufficient play relatively to each other when there is relative side motion between the frame and the truck.

Vhile I have shown the rocker arrangement embodied in a pony truck on the front of a locomotive. it is to be understood that the invention is not limited to its use in such trucks but it may also be used in trucks having two or more axles.

Having thus describcd the invention what is claimed and desired to be secured by Letters Patent is:

1. In a railway vehicle, the combination of a truck including a truck bolster, a body frame, a frame supporting member rigidly secured to the frame. and a rocker having means at its lower end whereby it is pivoted on said truck bolster, and also having a bearing surface on the top end thereof upon which said supporting member is mounted. said rocker and frame supporting member having interfitting parts.

In a locomotive, the combination of a truck including a truck bolster, a body frame, a frame supporting member rigidly secured to the frame above said bolster, and a rockerhaving openings at its lower eud'to receive pins whereby it is pivotally connected to said bolster, said rocker having a fiat supporting surface at the outer end thereof upon which said frame supporting member is .mounted, said rocker being pivoted so as to swing transversely of the locomotive.

3.
